A method for detecting the size of an automobile door frame

Abstract

The invention belongs to the technical field of detection fixtures and provides a fixture and a method for detecting the size of an automobile door frame. The fixture comprises a workbench and a fixed jig and a display computer which are arranged on the workbench, wherein a positioning mechanism is arranged on the fixed jig; a fixed sensing mechanism and a movable sensing mechanism which are used for detecting the size of the door frame are respectively arranged on the fixed jig; and a fixed distance sensor and a movable distance sensor are arranged in the fixed sensing mechanism and the movable sensing mechanism and are used for detecting size data of the door frame and transmitting the size data to the display computer for generating visible chart data. The fixture and the method have the advantages that due to the non-contact sensors, a door frame part can be automatically detected, and the problem that a narrow part and a thin-wall part cannot be directly detected by the sensors is solved; more than 20 sizes of door frames can be automatically detected at one time; and the fixture can automatically give an alarm, acquire the data and perform creatine phosphate kinase (CPK) analysis, is high in detection efficiency and precision and is convenient and quick.

Description

technical field [0001] The invention belongs to the technical field of automobile detection tooling, and relates to an automobile door frame size detection tooling and a detection method thereof. Background technique [0002] The output of automobile door frame parts is large, and the size requirements are high (mainly need to detect the surface contour size and line contour size), sometimes full inspection is required, and high-end customers also need to calculate CPK (process capability index), especially in the production of large customer manufacturers such as Toyota , Volkswagen and other car door frames, customers require calculation process capabilities, sometimes in a small space to detect important dimensions of the product, the traditional detection method is very inconvenient; the current detection method is to fix the door frame on the inspection tool, use a sharp Manual detection of angle feeler gauge generally requires two people to detect together, one person ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a vehicle door frame size detection tool for the current state of the art. The device has high detection efficiency and precise precision, and solves the problem that the sensor cannot be directly used for detection of parts in narrow spaces and thin-walled parts.
